E-Trade is one of the original online stock trading platforms. They survived the dot com boom and have only increased their offerings, lowered their fees, and become a more dominant trade platform.
While they lack the gamified user-optimized mobile platform of apps like Robinhood, they make it up in trustworthiness, account offerings, and overall features.
They offer a balance of tools for long-term retirement investing as well as for day trading. If you want a single platform that does everything, E-Trade is a solid option.
